To allwhom it may concern:

Be it known that I, FnnDERIo EOAUBERT, a citizen of the United States of America, and a resident of borough of Brooklyn, cit of New York, county of Kings, State of ew York, have invented certain new and useful Improvements in Methods of Separatmg Substances, of which the following is .a specification.

The present invention relates generall to a method. of separating liquids or solids old in suspension by liquids, and has more particular reference to a method of recovering odors from a retaining agent.

The object of the present invention is to devise an improved method of separating substances whereby a complete and absolute separation can be effected.

In the prior art of separating substances it is customary to subject materials to centrifugal separation. This process as practised however, has always taken place in a vessel or bowl having radial outlets allowing the contents to esca e radially as fast as it is solute separation is necessary, the process as.

heretofore practised allowing of radial escape cannot always be used -to advantage.

In carrying out my process I employ a containing vessel closed to radial escape of its contents and by this means I am enabled to subject the contents of the vessel to a continued centrifugal separation. This will cause the component parts of the contents of the vessel to be separated into what might be termed an inner core and an outside ring. This process is especiall useful where one of the component parts as a high freezing point inasmuch as the separation thus produced will then. cause the said component part to solidif or coagulate. If the com ponent part aving the higher freezing oint has the lower specific gravity it will orm a solid core surrounded by a liquid ring. In substances where the component part having the higher freezing point also has the greater s ecific be readily avity, an outside ring formation 0 the so 1d material will be produced surrounding a liquid core. It is obvious that the materials so separated can removed from the vessel, the liquid being simply drained on while the solid ortions formed are broken up or otherwise removed from the vessel. If the component part havin the higher freezing pointgwill not 'sohdify under the influence of the temperature of the air, the said solidification may be produced or facilitated, asthe case may be, by subjecting the contents of the vessel, while separating, to the influence of a refrigerant.

In the accompanying drawings is shown a containing vessel by means of which my improved process can be carried out.

In the said drawings Figure 1 represents a vertical sectional view on the line l1 of Ifig. 2 of a containing vessel used in connection with my improved process and Fig. 2 is a transverse horizontally sectional view on the line 2-2 of Fig. 1.

1 indicates a containing vessel closed to radial escape of its contents, as shown in the drawings, rotatably mounted in the bearings 2 and 3. A rotating motion may be imparted to this vessel by any suitable means but in the present instance the said vessel is provided with a pulley 4.- which, by means of the belt 5 receives power from the counter shaft 6 carrying the pulley 7. 8 indicates troughs which may be employed for the purpose of holding ice against the vessel as it rotates. The vessel is further rovided with a removable cover 9 and a va ve 10 at its lower end.

The method herein disclosed is more particularly adapted to be used in the manufacture of perfumes or in the art of recovering odors from a retaining agent. Thus for instance, a retaining agent such as fat, holding odors is introduced into the presence of a recovering agent, such as alcohol, for which the odors have a greater aflinity.

The two agents are then thoroughly mingled stand radially of the vessel. The mass thus formed'is them subjected to continued centrifugal separation until the particles of fat collected are solidified in a ring formation surrounding the alcohol which latter is left free in a liquid condition. During this action the odors have been transferred from the fat to the alcohol and are now available for use.

In the drawing 11 indicates the ring of fat formed ad'acent to the circumference of the vessel wh' e 12 indicates the liberated alcohol holding the odors.

What I claim is:

The method of transferring an odor-from a material holding it to another material, which consists in mixin the material holding the odor with anot er material having a greater attraction for said odor and havmg a difi'erent specific gravity and a lower melting point, exposing both materials in a lidifies, leaving the odor attracting material in a liquid form.
